ATTORNEY United States Fatent WINDOW AND STORM SASH ASSEMBLY Benoit M.Singleton, Middlebury, Ind., assignor to Woodlin Metal Products,Marshall, Mich., a corporation of Michigan Application May 3, 1956,Serial No. 582,413 Claims. (Cl. 189-69) The present invention relatesbroadly to window constructions, and in its specific phases to a windowassembly having an inbuilt storm sash as a part of same.

Double pane windows with a sealed air space are used for heat insulationpurposes, but such are satisfactory only as long as there is no leak ofair into the space between panes of glass since as soon as that happensthe window becomes subject to condensation of moisture on the innersurfaces between panes, and moreover such double pane windows areexceptionally expensive. This has led to the continuing use ofconventional storm sash with various ways of mounting same on the Windowframe, and even the use of clips for mounting a thin edged storm sashdirect on a window sash suited for house trailer use. The complete lackof a unitary window and storm sash construction especially adapted forhouse trailer use and commercially feasible, led to the conception anddevelopment of the present invention.

Accordingly among the objects of the present invention is the provisionof a window intended primarily for use such as in a house trailer and itaims to provide a new and improved construction for excluding cold.

A window sash is provided, said window sash having a metal frame and anelastic gasket which holds a light in said frame, and an object of theinvention is to provide a storm sash having a frame which lies againstand seals on a portion of said gasket.

Another object is to provide a novel construction for hingedly mountingthe window sash and the storm sash, each hinge comprising a flangeintegral with a frame member and having an integral curl at its outeredge, and another flange integral with a sash member and having anintegral bead turnably received in said curl.

A further object is to provide a frame construction which may bemanufactured from lengths of extruded metal, some of said lengths havingthe required flanges, curls and beads to form the sash hinges.

Still further objects and advantages of the present invention willappear as the description proceeds.

To the accomplishment of the foregoing and related ends, the invention,then, consists of the means hereinafter fully described and particularlypointed out in the claims, the annexed drawings and the followingdescription setting forth in detail certain means for carrying out theinvention, such disclosed means illustrating, however, but several ofvarious ways in which the principle of the invention may be used.

In the annexed drawings:

Figure l is an outer side elevation showing a construction in which boththe window sash and the storm sash are hingedly mounted at their upperedges.

Figure 2 is an enlarged fragmentary sectional view on line 22 of Figure1, looking in the direction of the arrows and with the window sash andthe storm sash being in closed position.

Figure 3 is a similar view but showing both sashes swung bodily outward.

Patented June 9, 19519 Figure 4 is a similar View but showing the windowsash closed and the storm sash swung outwardly.

Figure 5 is an outer side elevation showing a construction in which thewindow sash is hinged along one vertical edge and the storm sash alongits upper horizontal ed e.

The construction shown in Figures 1 to 4 will first be described. Inthese views, a window frame 7, a window sash 8, and a storm sash 9 areshown. The window frame 7, the frame 10 of the window sash 8, and theframe 1 1 of the storm sash 9 are all formed from extruded metal barssuitably joined at the corners of the respective frames.

In the following detail description, all reference numerals used will befound on Figure 2, whereas only the principal numerals have been appliedto Figures 3 and 4.

The upper member 12 of the window frame 7 is provided with an integral,outwardly projecting, longitudinal flange 13, the outer edge of saidflange being provided with an integral curl 14 extending in asubstantially straight line from end to end thereof. This curl 14extends downwardly at 15, inwardly at 16, and upwardly at 17 withrespect to the flange 13 and forms one element of a hinge for the windowsash 8.

The upper member 18 of the Window sash frame it) is provided at itsupper edge with an integral, outwardly projecting, longitudinal flange19 which underlies the flange 13, said flange 19 having a downwardly andinwardly curled outer edge forming a bead 243 which is turnably receivedin the curl 14, thus hingedly mounting the window sash frame It on thewindow frame 7.

Below the flange 13 of window frame 7, the upper member 18 of the windowsash frame it) is provided with a lower integral flange 13a having acurled outer edge 14a. This flange 13a and the curled edge 14a areidentical with the flange 13 and its curled edge 14 and detaildescription may therefore be dispensed with.

The upper member 21 of the storm sash frame 11 has an integral flange19a at its upper edge and underlying the flange 13a said flange 19ahaving a bead Ztla turnably received in the curl 14a to hin edly mountthe storm sash frame 11 on the window sash frame 10. The elemerits 13a,14a, 19a and Zila are duplicates of the elements 13, 14, 19 and 20 abovedescribed and further description may therefore be dispensed with.

The inner perimeter of the window sash frame It) is formed with achannel 22 in which an elastic gasket 23 is seated to mount the light24. This gasket 23 projects beyond the channel 22 as shown, and makespossible, in addition to supporting light 24, a side seal on the stormsash as will be hereinafter described.

The storm sash frame 11 has a channeled portion 25 in which a gasket 26is received for mounting the storm sash light '27. The inner side of thechanneled portion 25 lies against the side of the portion of the gasket23 which projects out of the channel 22, for weather exclusion. Thus asubstantially sealed air space is formed between sash lights 24 and 27to form an eflicient pocketed air space, and yet same has the advantagesof removability of the storm sash, and in case of moisture condensationbetween lights, same can be readily wiped away without the necessity ofremoving the storm sash.

A turn button 28 is shown for normally holding the storm sash frame 11against the gasket 23 but not sufficiently tight to cause seriousrelatively permanent sweating of the adjacent faces of lights 24 and 27,and yet such turn button makes it easy to pivotally swing the storm sashoutward for wiping away any condensation which may form on the innerfaces of the lights 24 and 27.

Both sashes 8 and 9 may be swung bodily outward as seen in Figure 3, orthe storm sash 9 may be swung outwardly from the window sash 8, as seenin Figure 4, thus making a very flexible type of construction.

The hinges for the two sashes effectively exclude'rain, and a weatherseal all around between the window sash frame 8 and the window frame 7may be'provided by using any suitable form of gasket 29, one type ofwhich is shown.

In Figure the window sash 30 is mounted on the window frame 31 by meansof a vertical hinge 32 of conventional type, and the storm sash 33 ismounted on said window sash 30 by means of a horizontal hinge 34constructed as above described.

From the foregoing, it will be seen that a novel and advantageous windowand storm sash construction has been disclosed for attaining the desiredends. However, it is to be understood that minor changes may be madetherein without departing from the spirit and scope of the invention asit has been described above.

Other modes of applying the principle of my invention may be employedinstead of those explained, change being made as regards the window andcombinations herein disclosed, provided the means stated by any of thefollowing claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention:
